The Prince of Wales showing is located 21 kilometres northeast of Vernon, near the headwaters of Putnam Creek.
In this area, Upper Triassic to Lower Jurassic Nicola Group sedimentary and volcanic rocks are faulted over metasedimentary rocks of the Proterozoic Silver Creek Formation. A porphyry dike of Mesozoic-Cenozoic age cuts the Nicola Group.
The light grey porphyry dike carries silver, lead, gold and molybdenum values. The 0.5 to 1.2 metre thick dike is impregnated with galena, pyrite and molybdenite and is exposed for up to 180 metres length on surface. The mineralized dike extends south to the Mystery showing (082LSW59).
By 1902 exploration was through tunnels and cross-cuts (at least 60 metres in length) and open cuts.
